Advancements in technology are changing the way prostate cancer is treated and cured. In the UK 46,000 men are diagnosed with prostate cancer each year with around 11,000 dying from the disease. New trials have seen incredible results, most notably reduced side effects and 49% of patients in complete remission.

The new treatment uses a drug, made from bacteria that live in the almost total darkness of the seafloor and which become toxic only when exposed to light.
Ten fibre optic lasers are inserted through the perineum - the gap between the anus and the testes - and into the cancerous prostate gland.
When the red laser is switched on, it activates the drug to kill the cancer and leaves the healthy prostate behind.
